In a deal announced this week, San Jose, Calif.-based Cisco, which earlier this year bought WebEx, let Santa Clara, Calif.-based Jamcracker Inc. provide its WebEx WebOffice applications as software as a service through carriers and resellers.

WebEx WebOffice includes document sharing, hosted e-mail, access to Web meetings, group scheduling and threaded discussions in one software application. It also includes a database with multiple templates. By offering WebEx WebOffice over Jamcracker’s JSDN, IT service providers can combine the application with other collaborate communications and IT services, including wireless messaging and security.

The JSDN provides single sign-on security for applications and service integration adapters, which connect the network to other vendors’ hosted software. Other Jamcracker partners include McAfee, Motorola, Research in Motion, Arsenal Digital and Postini.
